Just like the shape of an “O”, these Yo-Yos have a very rounded profile, that feel comfortable in your hand and smooth in play.

The rounded profile shape helps concentrate and distribute the weight in a peculiar way that is different to any other Yo-Yo. Due to the difference in shape, the weight distribution is actually closer to the center as opposed to the outside edges. This means its spin speed is slower but it also makes for a more controlled and mellow play. You just need one of these because learning to tame and dominate them is one of those experience you have to try.
